General info

Code

• This DIY electronic light is a good example of working with PWM pins.
• The rainbow colours are achieved by maximising and minimising the values of the individual LEDs, which we do using a for loop.
• With the colourToLED function we send the respective value to the LEDs.

Hardware

• The wiring is as simple as it gets. The light runs on an ATtiny25.
• We added three 3mm LEDs in red, green and blue to mimic the RGB LEDs and added 100 Ω resistors for the LEDs.
• The light is powered by a button cell battery.
